SKATE.

.LLPECEFICATION forming part of Letters Patent No. 311,763. dated February 3, 18815.

Application filed June- 9, 1884. (ModeL) To ctZZ whom it may concern.-

Be it known that I, CHARLES H. JonNsoN, a citizen of the United States, residing at Birmingham, in the county of New Haven and State of Connecticut, haveinventeda new and useful Improvement in Skates, of which the following is a specification.

This invention consists in the construction and arrangement of the parts, as hereinafter set forth and claimed.

In the drawings, Figure 1 is a side view of a skate constructed according to my invention. Fig. 2 is an inverted plan view thereof. Fig. 3 is a front view thereof. Fig. 4 is a view of the 1 blank which forms the heel-plate and its connections to the runner. Fig. 5 is a similar representation of the sole-plate.

a is the blade. I) is the sole-plate. c is the heel-plate. The sole-clamps cl d, curved in form, are pivoted togetherat 0, their rear ends.

To this same pivot is connected a bar, f, having longitudinal motion in line with the runner of the skate. The longitudinal movement of this barf back and forth imparts similar movement to the curved arms of the soleclamps d d, and thus causes the vertical jaws d d thereof to grasp and release alternately, according to the direction of the motion, the sole of a boot. h is a longitudinally-Sliding o heel-clamp bar,to which are attached the vertical jaws h h, intendedto grasp the heel of the boot. The inner ends of these two bars f and h are so connected that such ends can slide past each other by reason of the slot iin bar h, and the two rivet-bolts j j and boltheads j j, riveted rigidly into barf and passing down through the slotz' in the bar h.

To the barf, a short distance from its inner end, is pivoted on a short projecting arm, f, 0 a lever, is. The enlarged lower portion of this lever is constructed with a number of teeth, k. These teeth, on the turning of the leverhandle down toward the sole-plate, will en gage with a series of teeth, Z, in the contigu- 5 ous edge of the bar h. The brackets m mare riveted together, such rivet passing through a longitudinal slot, or, in the runner. This slot can be made sufliciently long for the required range of adjustment in the skate.

The heel-plate c is constructed out of one piece of sheet metal, stamped out so as to form on its outer edges projections for the brackets 0 o in the form of straps,whiclh,when bent down, are riveted to the skate-runner, as Seen at o. This attachment of the brackets leaves a space immediately underneath the sole-plate and between it and the runner for the passage of the bar 71, which construction serves to prevent any lateral motion of said bar in its back-and-forth movement. The 6 sole-plate b has similarly-constructed strapbrackets 11 p p p for its attachment to the posts Q q of the skate-runner. The brackets 12 Serve as a guide or protection to the movement of the curved arms of the sole-clamps, one passing on one side and the other on the opposite side of the post q. These brackets are riveted to the posts q q by the rivets qq.

r r are curved slots in the curved arms of the sole-clamps, through which pass the pins s s, riveted in the sole-plate, such pins securing the movement of the curved arms closely up against the under side of the sole-plate by means of the rivet-heads t t.

a is alug or projection on one side of the heel-plate, under which can be snapped the .outer end or handle of the lever it when the skate is locked to the boot or shoe on the skaters foot.

12 is a vertical stud or projection at the front s of the heel-plate, against which impinges the heel of the boot or shoe after such heel is brought up thereto by the inward movement of the heel-clamps.

The operation of the parts composing this 8 skate is as follows: The sole of the .boot or Shoe is placed on the sole and heel plates after the lever h is thrown back to the position as shown by dotted lines in Fig. 2 ofthe drawings. The ends of the barsf and h are then 0 made to approach each other until the jaws of the heel and sole clamps impinge upon the heel and sole of the boot. Then the lever is swung around, when its teeth 70 will engage with the teeth Z on the bar h, and a further 5 movement of the lever will bring it into the position shown by the full lines in Fig. 2, which will cause the full engagement of the teeth It of the lever with the teeth Z of the bar h, and the consequent completion of the drawing together of the two sets of clamps and the engagement of the jaws of said clamps with the heel and sole of the boot. Thus by a very simple movement and through a very efficient mechanism the two sets of clamps are made to engage with and secure the boot to the sole and heel plates. Then the handle of the ieveris sprung back of the lug a to retain such handle in place. The reverse of the abovedescribed movement of this lever will unlock the boot from the skate.

The construction of a longitudinal slot inthe skate-runner and arrangement therewith of the rear clamping device give a very wide range of adjustment, such range being limited only by the length of the slot.

Both the mechanism for such adjustment and for the locking and unlocking 0f the clamps are simple, and so arranged that they are durable and not liable to get out of order.

I claim- 1. In a skate, the combination of longitudinally-sliding sole and heel clamps and connectingbar with a stationary spur at the in ner end of the heel-plate, a toothed lever and longitudinally-sliding toothed bar to operate both sets of clamps simultaneously, and the skate-runner, substantially as described.

2. In a skate, the combination of longitudinally-sliding sole-clamps with sliding heelclamps, a slotted runner, and a stationary spur at the inner end of the heel-plate, a toothed lever, and longitudinally-sliding toothed bar to operate both sets of clamps simultaneously,

substantially as described.

3. The combination of the longitudinallysliding sole-clamps d d,having the connectingbarf, to which bar is pivoted the toothed lever k, with the sliding heel-clamp bar h, containing on its edge contiguous to the teeth is of the lever is a series of teeth, Z, substantially as described. 7

4. The combination of the longitudinallysliding sole-clamps dd, having theconnectingbar f, to which bar is pivoted the toothed lever k,with the sliding heel-clamp bar h, containing on its edge contiguous to the teeth 70 of the lever is a series of teeth, Z, said heelclamp bar being constructed with brackets m m, riveted together, and a runner containing a slot, n, substantially as described.
